cakephp - saveAll()在CakePHP 2.3.1中失败

我正在构建一个CakePHP 2.3应用程序，无法终生了解为什么saveAll始终失败。

我有以下型号:

Artist has很多ArtistPreview

ArtistPreview属于Artist

我使用Artist函数保存save()模型没有问题，但是，一旦我尝试使用saveAll方法，Cake似乎无法通过验证-这太疯狂了，因为我什至从模型中完全删除了所有验证规则。

这是我的观点，没什么疯狂的:

<?php
    echo $this->Form->create('Artist', array('inputDefaults' => array('class' => 'input-block-level')));
    echo $this->Form->input('Artist.name', array('label' => __('Name')));
    echo $this->Form->input('Artist.artist_section_id', array('label' => __('Section'), 'empty' => true));
?>
<label>Tags</label>
<div class="checkboxes">
    <?php echo $this->Form->input('Tag', array('label' => false, 'multiple' => 'checkbox', 'class' => false));; ?>
</div>
<?php
    echo $this->Form->input('Artist.website', array('label' => __('Website')));
    echo $this->Form->input('ArtistPreview.0.url', array('label' => __('Artist Preview')));
    echo $this->Form->input('Artist.description', array('label' => __('Description')));
?>
<?php

    echo $this->Form->submit(__('Add'), array('class' => 'btn btn-primary btn-large', 'div' => false)) . ' ';
    echo $this->Form->button(__('Cancel'), array('type' => 'button', 'class' => 'btn btn-large', 'div' => false, 'onclick' => 'closeDialog()'));
    echo $this->Form->end();
?>

这是我的add Controller 方法:

public function add() {
    $this->layout = 'form';

    if (!$this->request->is('ajax')) {
        throw new ForbiddenException();
    }

    if ($this->request->is('post')) {
        $this->setData($this->request->data['Artist'], array(
            'user_id' => AuthComponent::user('id'),
            'date' => $this->Date->gmt()
        ));
        if ($this->Artist->saveAll($this->request->data)) {
            $this->redirectAjax('/artists/view/' . $this->Artist->id);
        }
    }

    $this->set(array(
        'title_for_layout' => 'Add Artist',
        'artistSections' => $this->Artist->ArtistSection->find('list', array('order' => 'name')),
        'tags' => $this->Artist->Tag->find('list', array('order' => 'name'))
    ));
}

如上所述，saveAll方法每次都会失败。我检查了输出的内容，Cake用<div>类输出了一堆空白的error-message，但是没有消息。表单上的每个字段都会获得这些div之一。

现在，当我更改代码以使用save函数而不是saveAll时，除了ArtistPreview数据(可以预期的)之外，所有内容都会正确保存。甚至我的HABTM标签都已正确保存，并且没有任何事情无法通过验证。

从1.3天开始我就一直在使用Cake，所以我对此非常熟悉，甚至完全按照我在以前的项目中的要求进行了工作。我倾向于这是一个错误，除非我在这里丢失了一些东西。有任何想法吗？

编辑

我还尝试了saveAssociated方法，并在尝试保存时将deep键设置为true。这样可以保存艺术家，但是不能保存相关数据(ArtistPreview)。

根据要求，这是两个表:

-- -----------------------------------------------------
-- Table `artists`
-- -----------------------------------------------------
DROP TABLE IF EXISTS `artists` ;

CREATE  TABLE IF NOT EXISTS `artists` (
  `id` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
  `user_id` INT UNSIGNED NULL ,
  `artist_section_id` INT UNSIGNED NULL ,
  `artist_status_id` INT UNSIGNED NULL ,
  `name` VARCHAR(200) NULL ,
  `website` VARCHAR(500) NULL ,
  `description` TEXT NULL ,
  `date` DATETIME NULL ,
  `comment_count` INT UNSIGNED NOT NULL DEFAULT 0 ,
  PRIMARY KEY (`id`) ,
  INDEX `FK_artists_users_idx` (`user_id` ASC) ,
  INDEX `FK_artists__artist_sections_idx` (`artist_section_id` ASC) ,
  INDEX `FK_artists__artist_statuses_idx` (`artist_status_id` ASC) ,
  CONSTRAINT `FK_artists__users`
    FOREIGN KEY (`user_id` )
    REFERENCES `users` (`id` )
    ON DELETE SET NULL
    ON UPDATE CASCADE,
  CONSTRAINT `FK_artists__artist_sections`
    FOREIGN KEY (`artist_section_id` )
    REFERENCES `artist_sections` (`id` )
    ON DELETE SET NULL
    ON UPDATE CASCADE,
  CONSTRAINT `FK_artists__artist_statuses`
    FOREIGN KEY (`artist_status_id` )
    REFERENCES `artist_statuses` (`id` )
    ON DELETE SET NULL
    ON UPDATE CASCADE)
ENGINE = InnoDB;


-- -----------------------------------------------------
-- Table `artist_previews`
-- -----------------------------------------------------
DROP TABLE IF EXISTS `artist_previews` ;

CREATE  TABLE IF NOT EXISTS `artist_previews` (
  `id` INT UNSIGNED NOT NULL AUTO_INCREMENT ,
  `artist_id` INT UNSIGNED NULL ,
  `url` VARCHAR(500) NULL ,
  `date` DATETIME NULL ,
  PRIMARY KEY (`id`) ,
  INDEX `FK_artist_previews__artists_idx` (`artist_id` ASC) ,
  CONSTRAINT `FK_artist_previews__artists`
    FOREIGN KEY (`artist_id` )
    REFERENCES `artists` (`id` )
    ON DELETE CASCADE
    ON UPDATE CASCADE)
ENGINE = InnoDB;

这是我的setData函数，它仅合并两个数组。我没有使用隐藏字段，而是在 Controller 中设置了用户输入未填充的字段:

public function setData(&$original, $new) {
    $original = array_merge($original, $new);
}

最佳答案

所以我终于想通了，这真是个菜鸟错误。我想我昨天在编码时一定已经睡着了。问题出在我的模型中:

class Artist extends AppModel {
    public $belongsTo = array(
        'User',
        'ArtistSection',
        'ArtistStatus'
    );

    public $hasMany = array(
        'ArtistPicture',
        'Artist' // <--- problem was here, had 'Artist' instead of 'ArtistPreview'
    );

    public $hasAndBelongsToMany = array(
        'Tag'
    );

    public function __construct($id = false, $table = null, $ds = null) {
        parent::__construct($id, $table, $ds);

        $this->validate = array(
            'name' => array(
                'rule' => 'notEmpty',
                'message' => __('Artist name cannot be blank.')
            ),
            'website' => array(
                'rule' => 'url',
                'message' => __('Must be a valid URL.'),
                'allowEmpty' => true
            ),
            'artist_section_id' => array(
                'rule' => 'notEmpty',
                'message' => __('Section is required.')
            )
        );
    }
}

谢谢那些花时间研究这个问题的人，尽管我发布了错误的信息。
